MULTIPLE I/O TERMINAL
3-1-1 Overview
A MULTIPLE I/O TERMINAL is a modular PROFIBUS-DP Slave that consists of
a Communication Unit providing an interface to one or more I/O Units. The I/O
Unit interface supports up to 8 I/O Units and a total of up to 128 byte input + 128
byte output. I/O Units are connected using simple connections via I/O Unit
Connecting Cables. Allocation and address settings on the I/O Unit interface are
not required, enabling simple, flexible distributed I/O control.
3-1-2 System Configuration
Total number of input bytes: 128. Total number of output bytes: 128
3-1-3 Features
The Communication Unit and the I/O Units are separate, and the
Communication Unit and the I/O Units are connected through an I/O Unit
interface. I/O can be expanded simply by connecting additional I/O Units to the
I/O Unit interface.
Status information about the I/O Unit interface is transmitted as input data to the
PROFIBUS-DP Master Unit (two words).
The following I/O Units are available.
•
16- or 32-point Transistor Input Units (terminal block, connector, 25-pin D-sub
connector, or high-density connector)
•
16- or 32-point Transistor Output Units (terminal block, connector, 25-pin
D-sub connector, or high-density connector)
•
8-point/16-point Relay Output Unit
•
4- or 8-point Analog Input Unit (terminal block or connector)
•
4-point Analog Output Unit (terminal block or connector)
•
1-point Pulse Input Unit (high-speed counter)
Compared with fixed I/O Terminals, a high cost-performance ratio can be
achieved if I/O Units are used.
